Abstract (en)
[origin: WO0023257A1] Retroreflective elements comprising exposed-lens optical elements can be made by: (a) providing at least one retroreflective article comprising a monolayer of exposed-lens optical elements (12); a spacing layer (14); and a reflective layer (16); (b) forming a core layer (18); (c) attaching said retroreflective article onto said core layer yielding a retroreflective composite; and (d) dividing said composite into retroreflective elements. The retroreflective elements can be retroreflective under dry and/or wet conditions, and can be placed on selected surfaces.
